[ Open in Perplexity ](https://www.perplexity.ai/search/new?q=Read%20from%20https%3A%2F%2Fscrapfly.io%2Fdocs%2Fproxy-saver%2Fcertificates%20so%20I%20can%20ask%20questions%20about%20it.) To use Proxy Saver with HTTPS and SSL connections you need to configure your proxy tool to trust the Scrapfly Proxy Saver TLS certificate or ignore certificate verification process. Here's how to do it with popular proxy tools. ## Quick Install Run this one-liner to automatically install the certificate for your OS (Linux, macOS, WSL): ``` curl -sL https://scrapfly.io/install-ca.sh | sh ``` ## Download the Certificate Download the certificate directly: ``` curl -o scrapfly-ca.crt https://scrapfly.io/ca.crt ``` Or find it in the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) under each proxy profile. ## Container Configuration When using Docker, you can download and install the Proxy Saver certificate directly during the image build: - [ Debian ](#debian-image) - [ Alpine ](#alpine-image) ``` # Dockerfile example for Debian-slim FROM debian:bullseye-slim # Install ca-certificates and curl RUN apt-get update && apt-get install -y --no-install-recommends \ ca-certificates curl && \ rm -rf /var/lib/apt/lists/* # Download and install the Proxy Saver certificate RUN curl -fsSL -o /usr/local/share/ca-certificates/scrapfly-ca.crt https://scrapfly.io/ca.crt && \ update-ca-certificates ``` ``` # Dockerfile example for Alpine FROM alpine:latest # Install ca-certificates and curl RUN apk add --no-cache ca-certificates curl # Download and install the Proxy Saver certificate RUN curl -fsSL -o /usr/local/share/ca-certificates/scrapfly-ca.crt https://scrapfly.io/ca.crt && \ update-ca-certificates ``` ## HTTP Tools Each CLI tool like `curl` has a custom certificate option using which we can specify the location of the Proxy Saver `scrapfly-ca.cert` certificate file: - [ CURL ](#curl-basic) - [ HTTPIE ](#httpie-basic) ``` curl \ --cacert /path/to/scrapfly-ca.crt \ --proxy=http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333 \ https://httpbin.dev/anything ``` ``` http \ --verify=/path/to/scrapfly-ca.crt \ --proxy=http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333 \ https://httpbin.dev/anything ``` Alternatively, each tool also provides an ability to **ignore certificate verification process** which means the certificate step can be ignored entirely though it's not recommended due to security risks. - [ CURL ](#curl-ignore) - [ HTTPIE ](#httpie-ignore) ``` curl \ --verify=no \ --proxy=http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333 \ https://httpbin.dev/anything ``` ``` http \ --verify=no \ --proxy=http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333 \ https://httpbin.dev/anything ``` ## Operating Systems The certificate can also be installed in the operating system certificate store to make it available for all applications. - [ Windows ](#windows) - [ macOS ](#macos) - [ Linux ](#linux) 1. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) 2. Double click the `.crt` file 3. Follow the Windows instructions to install the certificate 4. Reboot your computer 5. After rebooting, you will be able to connect to Proxy Saver > To verify whether the certificate was installed correctly use this windows command: ``` > curl -v -x \ > http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io \ > https://httpbin.dev/anything > # if the certificate was not installed correctly you'll see: > # curl: (60) SSL certificate problem: unable to get local issuer certificate > ``` 1. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) 2. Double click the `.crt` file 3. Select "Always Trust" in the "When using this certificate" options dropdown. 4. Reboot any active programs to be able to connect to Proxy Saver > To verify whether the certificate was installed correctly use this macos command: ``` > curl -v -x \ > http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io \ > https://httpbin.dev/anything > # if the certificate was not installed correctly you'll see: > # curl: (60) SSL certificate problem: unable to get local issuer certificate > ``` 1. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) 2. Copy the `.crt` file to `/usr/local/share/ca-certificates/` 3. Run `sudo update-ca-certificates` 4. Reboot any active programs to be able to connect to Proxy Saver > To verify whether the certificate was installed correctly use this linux command: ``` > curl -v -x \ > http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io \ > https://httpbin.dev/anything > # if the certificate was not installed correctly you'll see: > # curl: (60) SSL certificate problem: unable to get local issuer certificate > ``` ## Web Browsers Each web browser can also take custom certificates to trust HTTPS connections certified by Proxy Saver. - [ Chrome/Chromium ](#chrome) - [ Firefox ](#firefox) 1. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) 2. Go to browser's certificate settings page `chrome://settings/certificates` 3. Go to the **Authority** tab and select **Import** to upload your `scrapfly-ca.crt` file. 4. When prompted for confirmation select all checkboxes and import 1. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver) 2. Go to browser's certificate settings page `about:preferences#advanced` 3. Go to the **Privacy & Security** tab and select **View Certificates** 4. Upload your `scrapfly-ca.crt` file. 5. When prompted for confirmation select all checkboxes and import ## HTTP Client Libraries Most http client libraries support proxies and can be configured to use custom certificates. Here are some examples for the most popular http client libraries: - [ requests ](#python-requests "python") - [ httpx ](#python-httpx "python") - [ curl ](#php-curl "php") - [ guzzle ](#php-guzzle "php") - [ fetch ](#nodejs-fetch "nodejs") - [ net/http ](#go-nethttp "golang") - [ reqwest ](#rust-reqwest "rust") - [ typhoeus ](#ruby-typhoeus "ruby") ``` import requests response = requests.get( "https://httpbin.dev/anything", proxies={ "https": "http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333" }, # use scrapfly certificate verify="/path/to/scrapfly-ca.crt", # or disable verification entirely # verify=False ) # or set for entire session session = requests.Session() session.verify = "/path/to/scrapfly-ca.crt" session.verify = False session.proxies = { "https": "http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333" } ``` ``` import httpx response = httpx.get( "https://httpbin.dev/anything", proxies={ "https://": "http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333" }, # Use scrapfly certificate verify="/path/to/scrapfly-ca.crt", # Or disable verification entirely # verify=False ) # or set for entire session client = httpx.Client( verify="/path/to/scrapfly-ca.crt", # Or disable verification entirely # verify=False proxies={ "https://": "http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333" } ) response = client.get("https://httpbin.dev/anything") print(response.text) client.close() ``` ``` ``` ``` [ 'https' => 'http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333' ], // Set the path to the custom certificate 'verify' => '/path/to/scrapfly-ca.crt' // If you want to disable SSL verification entirely, set 'verify' to false // 'verify' => false ]); // Send a GET request $response = $client->get('https://httpbin.dev/anything'); // Print the response body echo $response->getBody(); ?> ``` ``` const { HttpsProxyAgent } = require('https-proxy-agent'); const https = require('https'); const fs = require('fs'); // Proxy configuration const proxy = "http://proxyId-XXX:API_KEY@proxy-saver.scrapfly.io:3333"; const agent = new HttpsProxyAgent(proxy); // Path to custom certificate const cert = fs.readFileSync("/path/to/scrapfly-ca.crt"); // HTTPS agent with custom certificate const httpsAgent = new https.Agent({ ca: cert }); // Individual request with custom certificate and proxy fetch('https://httpbin.dev/anything', { agent: httpsAgent, agent: agent // Attach proxy agent as well }) .then(response => response.text()) .then(text => console.log(text)) .catch(err => console.error('Request failed', err));

You can also install the certificate at the [operating system level](#operating-system) to make it available for all browser libraries. - [ Selenium ](#selenium) - [ Playwright (Python) ](#playwright-py) - [ Playwright (JS) ](#playwright-js) - [ Puppeteer ](#puppeteer) 1. Ensure you have the required Python packages installed: ``` pip install selenium ``` 2. Download the certificate file from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver). 3. Use the following Python code to load the custom certificate into Selenium's browser session: ``` import os import selenium.webdriver as webdriver from selenium.webdriver.chrome.options import Options # Create a new ChromeOptions instance chrome_options = Options() # You can ignore all certificate errors: chrome_options.add_argument(f"--ignore-certificate-errors") # or add proxy saver certificate cert_path = "/path/to/proxy-saver.crt" chrome_options.add_argument(f"--ssl-client-certificate-file={cert_path}") # Initialize WebDriver with the options and test it: driver = webdriver.Chrome(options=chrome_options) driver.get("https://httpbin.dev/anything") # if the certificate was not installed correctly you'll see: # SSL certificate problem: unable to get local issuer certificate ``` 1. Ensure you have the required Python packages installed: ``` pip install playwright ``` 2. Download the certificate file `scrapfly-ca.crt` from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver). 3. Use the following Python code to load the custom certificate into Playwright's browser session: ``` import asyncio from playwright.async_api import async_playwright async def run(): async with async_playwright() as p: # Launch browser with the custom certificate browser = await p.chromium.launch(headless=False) context = await browser.new_context( # you can ignore certificates ignore_https_errors=True, # and add custom certificate: extra_http_headers={ "client-certificate": "/path/to/certificate.crt" } ) # Connect to a page to test the certificate page = await context.new_page() await page.goto("https://httpbin.dev/anything") # Print page content to verify print(await page.content()) await browser.close() asyncio.run(run()) ``` 1. Ensure you have the required NPM packages installed: ``` npm install playwright ``` 2. Download the certificate file `scrapfly-ca.crt` from the [Proxy Saver dashboard](https://scrapfly.io/dashboard/proxy-saver). 3. Use the following Javascript code to load the custom certificate into Playwright's browser session: ``` // Import Playwright const { chromium } = require('playwright'); (async () => { // Launch the browser with ignoreHTTPSErrors set to true const browser = await chromium.launch({ headless: false }); const context = await browser.newContext({ ignoreHTTPSErrors: true // Ignore SSL errors (useful for self-signed certs) }); // Open a new page const page = await context.newPage(); // Navigate to the target URL await page.goto('https://your-internal-url-with-cert.com'); // Print the page content to verify it loads correctly console.log(await page.content()); // Close the browser await browser.close(); })(); ``` 1. Ensure you have the required NPM packages installed: ``` npm install puppeteer ``` 2. Use the following Javascript code to ignore certificate checks: ``` // Import Puppeteer const puppeteer = require('puppeteer'); (async () => { // Launch the browser with ignoreHTTPSErrors set to true const browser = await puppeteer.launch({ headless: false, args: ['--ignore-certificate-errors'] // Ignore SSL certificate errors }); // Create a new browser context/page and navigate to url const page = await browser.newPage(); await page.goto('https://httpbin.dev/anything'); // Print the page content to verify it loads correctly const content = await page.content(); console.log(content); await browser.close(); })(); ``` 3. Optional: as Puppeteer doesn't support custom certificates you can install the system level certificate using [operating system instructions](#operating-system).
